status

 

Gyrophaena simulans Seevers, 1951   Fig. 25A-G View Figure 25

Material

(DNA barcoded specimens). Canada: Ontario: Hartington, Eel Lake Cottage , 44.563, -76.549, deciduous forest, mushrooms, 4.X.2017, M. Pentinsaari (2, CBG) GoogleMaps   .

Distribution.

Origin. Nearctic. Canada: ON [new record]. United States: IL, MD, PA.

Diagnosis.

Gyrophaena simulans   is extremely similar to G. criddlei   and G. pseudocriddlei   but has a slightly more transverse and flatter pronotum, with straighter apical and basal margins, and differently shaped upper process of the median lobe in lateral view (Fig. 25B View Figure 25 ): longer than that of G. pseudocriddlei   but shorter and broader than that of G. criddlei   . The emargination of male tergite VIII in G. simulans   appears to be shallower and broader than that of G. criddlei   but more specimens are needed to confirm this.

Bionomics.

The Canadian specimens were collected by sifting mushrooms in a deciduous forest. No detailed data on the host fungus were recorded.

Comments.

Gyrophaena simulans   is a native Nearctic species distributed in eastern North America and is newly reported from Canada. The barcode cluster BOLD:ACY8004 also contains specimens identified as related species G. criddlei   (female) and G. pseudocriddlei   but more research, with broader sampling of sequenced, identified males, is needed to determine whether these species share a BIN or these specimens are misidentified. As we were unable to verify the identifications at this time, these records are not published here.
